No straw bans here (yet), but I have a straw report. My car is basically fueled by diet cola. Unfortunately, McDonald's discontinued caffeine-free Diet Coke awhile back, so if I go to Mickey D's I have to settle for a substitute (I'm not allowed ANY caffeine, and the consequences of ignoring that are serious). Burger King, however, does still offer caffeine-free Diet Coke.
I often arrive at home base with a large drink cup (with lid and straw) in the center console. The cups have a number of uses, so I stockpile a number of those, and I started keeping the straws in a cup next to the kitchen sink for use when pouring a cola at home. What I discovered is that the McDonald's straws, which are white with colored stripes, hold up seemingly indefinitely. The Burger King straws, which are red, don't seem to like UV radiation. Ad=fter a very short time, they get so brittle that they break just from picking them up.
